It is equivalent to: 3x+6+5 = 3x+11
0.5
3x + 3x + 3x = 3* (3x) = 9x
6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6

It is equivalent to: 3x+6+5 = 3x+11
It is equivalent to: 3x+6+5 = 3x+11
equivalent to 3x -6 = -9; so 3x = -9 + 6; so 3x = -3 so x = -1. Check: -6 + (3 * -1) = -6 + (-3) = -9 QED
0.5
It is equivalent to: 3x+6+5 = 3x+11
(6-4x)(x-2)+3x =6x-12-4x+8x+3x =5x-4
3x + 3x + 3x = 3* (3x) = 9x
It depends on what it is meant to be equivalent to!
I think this is what you're asking for.3x=9 can be moved to be x=9/3For a slope/intercept example:3x-6y=-1 Subtract the 3x-6y=-3x-1 Divide the negative 6 on yy=1/2x+1/6 And there, (y=1/2x+1/6) is equal to (3x-6y=-1)
3x+6
If you mean: 3x-(2x+4x-6) then 3x-2x-4x+6 simplifies to 6-3x
